      Description
        Starts the application in production mode.

      Usage
        $ next start <dir> -p <port>

      <dir> represents the directory of the Next.js application.
      If no directory is provided, the current directory will be used.

      Options
        --port, -p      A port number on which to start the application
        --hostname, -H  Hostname on which to start the application (default: 0.0.0.0)
        --keepAliveTimeout  Max milliseconds to wait before closing inactive connections
        --help, -h      Displays this message
